Patent JP-H01216607-A (JP)
Title: Amplifier circuit
Inventor: ETO TOSHIYUKI
IPC: H03F3/343
Filed: 1988-02-24
Abstract: PURPOSE:To prevent the generation of waveform distortion and to reduce the power consumption by adopting the constitution such that a 1st transistor(TR) whose drain is connected to an input terminal of a current mirror circuit and a 2nd TR whose source is connected to the output terminal of the current mirror circuit. CONSTITUTION:An output current is supplied from a TR Q2 in a positive half cycle of an input signal V1, a drain current of the TR Q2 in this case is the sum of an output current and a drain current of a TR Q4 and a TR Q1 is driven in the OFF state by the input signal V1. Thus, the drain current of the TR Q4 is decreased and the drain current of the TR Q2 is nearly equal to the output current. Moreover, in a negative half cycle of the input signal V1, the output current is supplied from the TR Q4, and as the amplitude of the input signal V1 increases, the drain current of the TR Q1 is increased. Thus, the drain current of the TR Q4 is increased, then the increase in the output current is sufficiently supplied to prevent the generation of wavelength distortion.

Title: Digital phase locked device
Inventor: SHIMADA TOSHIYUKI
IPC: H03L7/06
Filed: 1985-03-05
Abstract: PURPOSE:To attain the satisfactory follow-up characteristics as well as the low cut-off characteristics by using a frequency detuning answer loop which responds to the gentle increase/decrease of an input phase signal. CONSTITUTION:A code memory part 9 stores continuously the phase error signal codes in plural times and delivers them in the form of a code train when the phase error signal phie has meaning. A frequency detuning detecting part 10 delivers the positive value when the codes of a code train delivered from the part 9 are all positive and then delivers the negative value if those codes are all negative. Otherwise the part 10 delivers 0. A switch control part 7 controls a switch 8 and delivers the output of an attenuator 2 to an adder 4 when the signal phie has meaning. Then the output of the part 10 is delivered to the adder 4 when an input phase signal is applied. Otherwise the switch 8 is turned off. Therefore the output of both parts 2 and 10 are delivered smoothly to the adder 4 in case the input phase signal is applied rather discretely.
